R33 Stock Turbo

[Dush]

Boyz and girlz of all ages, I have a quick question...

The Stock turbo on a R33 Skyline.. how good is it really.

How much boost can be reached threw it at a safe level and what steps are needed to do that?

a T3 turbo, is it a stright bolt on to the RB25DET?

the other day I turned the boost slightly up to 10psi.

sometime when i give it, the car sergues?? anyone knows whats up?

Thankx guys

The stock turbo is prone to lamination on the exhaust wheel and can disintergrate but sayin that I dont know how many have done this or when it will occur.

With a stock intercooler 10psi is pushing the intercooler's flow rate and could/most probably be why your are getting surges.

To run high boost pressures you will have to upgrade the intercooler at least, if not your fuel system as well and a engine management system to do it properly. the last two struggle to run your engine at above standard settings and can result in detonation due to lean running.

As to the T3 I dont know but am interested to find out as I am looking for a bolt on higher flowing turbo.

i run 12psi (0.8bar) but its advice to run a FMIC with that mount of boost

the Save level (limit) is 12psi

Thankx guys. um.. whats a FMIC??

Should i wind the boost down??

Front mount intercooler.

If you want to mod your car cheaply, get a fmic, exhaust, filter upgrade and add a little boost.

Any more and you're going to have to start looking at computers and then turbos.

My stocky is pushing 202.2rwkw with 13.5psi of boost, FMIC, full turbo back, PFC, Adjustable exhaust cam gear... Been going 7 months no probs!

i got a Front mount cooler, just need to install it. I'm thinkin about a piggy back computer? apexi AVCR or a SAFC, will these help wit the mapin go the fule and air??

[race_snooze]

search...

but yes t3 is the same size (same flange)

as for boost level have said this a few times now. A lot of us have been running 12psi for ages on stock turbo.

I have been running mine on 12 for 2 years.

r33, remapped 32 comp, exst, fmic, no idea of any internals, stock turbo

216wrkw last dyno. (tuning tool only)

Dont do it with stock everything else other wise you will get boost cut.

The safc will help with your fuel and air mix when tuned properly. See a reputable tuner. The AVCR will not map air and fuel it is a boost controller.

thankx guy, I've droped my car off at J-sepc In mnelbourne to fit my FMIC, i'm thing of a Pule pump upgread and injectors to stop the surges.. what u think?

[The Mafia]

the fuel pump and injectors will do nothing, as it will be a waste of money.

Fuel pump if you are going to push more than 180rwkw out of it.

The surge will be it boost cutting. You'll find that even though you are running 10psi of boost, it'll either have a restriction somewhere, or you'll be spiking and hitting the boost cut (which hits at 12psi) and doing to good old rich and retard.
